Answer: C (-7/18)
Step-by-step explanation: you flip the denominator and numerator and keep the negative
Answer:12-14
Step-by-step explanation:
Answer:
2. This is only true when x=-3.
3. This is only true when x=3.
4. This is only true when x=12.
5. This has no solution.
6. This has an infinite number of solutions.
Answer:
y variable will be elimited when adding the system of equations
x = 2 or y = 3
Step-by-step explanation:
- x + 6y = 16
8x - 6y = -2
Add both equations
(-x + 8x) + {6y + (-6y)} = 16 + (-2)
7x + 6y - 6y = 16 - 2
7x + 0 = 14
7x = 14
x = 14/7
x = 2
- x + 6y = 16
- 2 + 6y = 16
6y = 16 + 2
6y = 18
y = 18/6
y = 3
the x variable will be eliminating when adding the system of equations and the
y variable will be elimited when adding the system of equations
or the sum of the system equations is negative 8X = 14 or
x = 2 or y = 3
or there's only one solution to the system equations
